Battery EEPROM Works
Hardware
The hardware of Battery EEPROM Works is based on Philips I2C Parallel Port adapter.
Socket P1 is used to connect 24C0X chips, P4 is used to connect 25LC040 and M95640. Other supported chips must be connected to sockets P2 or P3 depending on package. The fastest way to find the right socket (P2 or P3) is just to try to read the chip.
R7, R8, D1 and D2 are used to protect adapter and LPT port from overvoltage.
PCB design for single sided board can be found in your installation directory .
